To address these issues, this study analyzed the discrepancies between cases known to Child Protection Services (CPS) agencies and those known to professionals who regularly come into contact with children: teachers, hospital personnel, law enforcement officers, court personnel, and social service workers. The analysis was based on the 1980 and 1986 National Study of the Incidence and Prevalence of Child Abuse and Neglect. The research yielded three major findings. First, older victims were less likely than younger victims to be known to CPS agencies. Second, there was a hierarchy of type of abuse reported to CPS agencies, with sexual abuse being at the top of the list and educational neglect at the bottom of the list. Third, the victims' race, sex, and income did not have a role in determining whether or not a case was reported to CPS agencies. 4 tables and 4 references
